Root-knot nematodes (Meloidogyne spp.) are the most common and destructive plant-parasitic nematode group worldwide and adversely influence both crop quality and yield. In this study, a total of 51 root-knot nematode populations from turfgrasses were tested, of which 44 were from North Carolina, 6 from South Carolina and 1 from Virginia. Molecular characterisation was performed on these samples...

Granular and liquid commercial humates, with micronutrients, and a microbial fermentation product were compared in several combinations with nematicides for their effects on cotton lint yield and root-knot nematode suppression. Fumigant nematicides effectively reduced cotton root galling caused by root-knot nematodes, and cotton lint yields increased. Organophosphates and carbamates were not ef...

Millet, milo, soybean, crotalaria, and Norman pigeon pea were used in conjunction with clean fallow and a nematicide (fensulfothion) for managing nematode populations in the production of tomato transplants (Lycopersicon esculentum Mill.). Glean fallow was the most effective treatment in suppressing nematode numbers. After 2 years in tomato, root-knot nematodes increased in numbers to damaging ...

A screening of several Chinese medicinal herbs for nematicidal properties showed that Arisaema erubescens (Wall.) Schott tubers possessed significant nematicidal activity against the root-knot nematode (Meloidogyne incognita). From the ethanol extract, two nematicidal flavone-C-glycosides were isolated by bioassay-guided fractionation. The compounds were identified as schaftoside and isoschafto...

This study was conducted to identification and distribution Root-knot nematode species in lavender fields where Lavandin (Lavandula × intermedia Emeric ex Loisel. var. Super) cultivated an area of about 625 ha Isparta Burdur Provinces Turkey. A total 60 samples were collected autumn 2020. Root knot molecular determined by species-specific primers from egg masses. The 17 taken found be infected ...

greenhouse studies showed in the transplant of tomato that two weeks before infection with nematodes with two species of mycorrhizal g. mosseae and g. intraradices had been inoculated, were significantly offseted the reduction of growth that had been done by nematodes. it should be noted that the percentage of root colonization with two species 66.3% and 62.2% respectively and based on this stu...

When nematodes invade and subsequently migrate within plant roots, they generate cell wall fragments (in the form of oligogalacturonides; OGs) that can act as damage-associated molecular patterns and activate host defence responses. However, the molecular mechanisms mediating damage responses in plant-nematode interactions remain unexplored. Here, we characterized the role of a group of cell wa...

in this study, high biocontrol potentially bacillus isolates, against root knot nematode were evaluated from viewpoint of biofilm formation and root colonization in vitro. among 139 bacillus isolates from tomato rhizosphere of several regions of razavi khorasan, 15 strains which show more ability to prevent egg hatch and cause larvae mortality of meloidogyne javanica, were tested in biofilm ass...

The endoparasitic nematophagous fungus Meria coniospora reduced root-knot nematode galling on tomatoes in greenhouse pot trials. The fungus was introduced to pots by addition of conidia at several inoculum levels directly to the soil or addition of nematodes infected with M. coniospora to the soil; both methods reduced root galling by root-knot nematodes. These studies represent a part of a rec...
